According to NeoGaf user Ryce, who has a history of leaking accurate information about Marvel vs Capcom Infinite in the past, has some new information to share about Marvel vs Capcom’s roster. The roster is as follows:
Rocket/Groot (this is how the character was named to me; I’m not sure if it’s just Rocket Raccoon with Groot assists or a redesigned character actually called Rocket/Groot)
The roster seems to follow what we’ve been hearing since before the game was even officially revealed, no X-Men. Instead, Marvel’s side will have a much heavier focus on the Marvel Cinematic Universe.
Judging by fan feedback to the alleged roster, fans aren’t exactly pleased. Omissions of fan favorite characters like Phoenix Wright, Amaterasu, Viewtiful Joe, Dormammu, Dr.Doom, Deadpool, and so, on are leaving fans disappointed. Another common complaint was the lack of female characters in the base roster, with only 4 females. And judging by the feedback, Black Panther seems like the most popular character on the Marvel side that people were hoping for and expecting. Marvel vs Capcom 3 was already lower than its predecessor, and was heavily criticized for it, and Marvel vs Capcom Infinite’s roster is apparently lower than that, with only 28 characters.
This is all still rumors until Capcom reveals the roster themselves. Marvel vs Capcom Infinite is expected to launch in September 19, 2017 for PS4, XBOX ONE, and PC.
